Award-Session Session 15:30 Deluxe preset

Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Session 15:30 Deluxe Studio Combo was drawn in 1981 by Axess Electronics of Basingstoke, the makers of Award-Session. One 12AX7 provides two gain stages with a volume, a Normal/Bright/Mid Boost switch, an input sensitivity switch and a two-position EQ with bypass; a second 12AX7 is the long-tail phase inverter. Two cathode-biased 6L6GCs (KT66, EL34 and others listed) run off a solid-state bridge, with a 15/30-watt switch, foot volume jack, preamp out and record output.

Schematic-derived preset files for 16 Fractal and Line 6 modelers: Axe-Fx II/XL/XL+, Axe-Fx III, FM3, FM9, and the full Helix family (Floor, LT, Rack, HX Stomp, HX Stomp XL, Native).

Gridleak extracts amp parameters from original circuit schematics using AI vision — component values, gain staging, tone stack topology, tube types — then generates native preset files for every supported modeler. Every extraction is scored 0–100 and the score is published.
